Cyazofamid (Ref: IKF 916)
(Not known by any other names)
SUMMARY
Cyazofamid is a foliar fungicide. It has a low aqueous solubility, is unlikely to leach to groundwater and is volatile. It is not persistent in soils or aquatic systems. Whilst it has a low mammalian toxicity there is some concern regarding its potential for bioaccumulation. It is a skin and eye irritant. It is moderately toxic to birds, most aquatic organisms, honeybees and earthworms.
